Thanks Artisi. They are headbox fan pumps. I have involved both the pump and headbox supplier. Neither recomended it or have seen it on a single layer headbox. But pressure from management spurred me to explore the concept more. I chose this forum just to hear from some pump experts in other...
Thanks BigInch.
My pump and system curves are fairly perpindicular with the existing pump.
So forget my idea of balancing the two pumps with a pair of PT's. You're right, physics dictates they will balance at the intersection and it still comes back to the system & pump curves.
To clarify...
I have a double suction centrigual pump in a papermaking application. Goulds3420 30x36-42 Lo pulse impeller. Powered by two 1000hp DC motors. Motors controled by a drive at a speed to meet a downstream pressure setpoint. (Pump TDH=150-200ft. Q= is 25k-40k gpm) Needing more pressure/flow at...
